Chapter 61 Information Technology For Management 6 th Edition Turban, Leidner, McLean, Wetherbe Lecture Slides by L. Beaubien, Providence College John Wiley & Sons, Inc. Mobile, Wireless and Pervasive Computing
Chapter 62 Learning Objectives Discuss the characteristics and attributes of mobile computing and m-commerce Describe the drivers of mobile computing Understand the technologies that support mobile computing Describe wireless standards and transmission networks Discuss m-commerce applications in financial and other services, advertising, and providing of content Describe the applications of m-commerce within organizations
Chapter 63 Learning Objectives (Continued) Describe consumer and personal applications of m- commerce Describe some non-Internet m-commerce applications Describe location-based commerce (l-commerce) Discuss the key characteristics and current uses of pervasive computing Describe the major inhibitors and barriers of mobile computing and m-commerce
Chapter 64 Mobile Computing – Value Chain M-commerce is a complex process involving a number of operations and entities (customers, merchants, mobile operators, etc.).

Chapter 65 Problems with Wi-Fi Roaming – users cannot roam from hotspot to hotspot if the hotspots use different Wi-Fi network services Security – because Wi-Fi uses radio waves, it is difficult to protect Cost – commercial Wi-Fi services are low cost but not free and each service has its own fees and separate accounts for users to logon
Chapter 66 WiMax Worldwide Interoperability for Microwave Access, popularly known as WiMax, is the name for IEEE standard 802.16 Wireless access range of up to 31 miles; Data transfer rate of 75 Mbps; Secure system that offers voice and video.
Chapter 67 Mobile Computing Infrastructure – WWAN’s
Chapter 69 Mobile Computing – L-Commerce Applications
Chapter 610 Managerial Issues Comparing wireless to synchronized mobile devices. In many cases, transmitting data in the evening or using a docking device is sufficient. In others, real time communication is needed, justifying a wireless system. Timetable. Although there has been much hype about m-commerce, only a small number of large-scale mobile computing applications have been deployed to date. The most numerous applications are in e-banking, stock trading, emergency services, and some B2B tasks. Companies still have time to carefully craft an m-commerce strategy. Setting applications priorities. Finding and prioritizing applications is a part of an organization’s e-strategy. Although location-based advertising is logically attractive, its effectiveness may not be known for several years. Therefore, companies should be very careful in committing resources to m- commerce. For the near term, applications that enhance the efficiency and effectiveness of mobile workers are likely to have the highest payoff.
Chapter 611 Managerial Issues (Continued) Just a buzzword? In the short run, mobile computing, m- commerce, and especially l-commerce, may be just buzzwords due to the many limitations they now face. However, in the long run, the concepts will be increasingly popular. Management should monitor the technological developments and make plans accordingly. Choosing a system. The multiplicity of standards, devices, and supporting hardware and software can confuse a company planning to implement mobile computing. An unbiased consultant can be of great help. Checking the vendors and products carefully, as well as who is using them, is also critical.
